Smart cement paste with carbon nanotubes

2016
Carbon nanotubes can be added to cementitious materials to create a multifunctional nanocomposite with excellent piezoresistive and strain-sensing properties. The use of carbon nanotubes provides high strain sensitivity and signal-to-noise ratio, which are ideal for fabricating self-sensing nanocomposite cement paste for applications to structural ...

Determination of Roxarsone Using Carbon Paste and Amberlite LA2 Modified Carbon Paste Electrodes

Electroanalysis, 2000
The methods for determination of the growth promoter 4-hydroxy-3-nitrobenzenearsonic acid (Roxarsone) in veterinary product and in poultry drinks have been developed using differential pulse voltammetry with carbon paste and Amberlite LA2 chemically modified carbon paste electrodes.

Ensembles of carbon paste microelectrodes

Analytica Chimica Acta, 1999
Abstract In this paper, the design of the carbon paste and reference microelectrodes and “carbon paste needle-microelectrodes” (CPNMEs) system is reported (including a 140 μm diameter carbon paste electrode, a 150 μm diameter Ag/AgCl reference electrode and a No. 9 syringe needle auxiliary electrode).

The carbonation of hardened cement pastes

Advances in Cement Research, 1990
The microstructure of hardened pastes of C3S and a C3S/silica fume blend have been examined by transmission electron microscopy before and after partial carbonation in pure CO2 at a relative humidity of 72·6%. Fibrillar outer product C-S-H and the outer regions of inner product C-S-H gel carbonate without change of morphology to silica gel.

On the past and present of carbon nanostructures

physica status solidi (b), 2011
AbstractA personal review is presented on 50 years of my research experiences in working on research on carbon science and carbon‐based nanostructures. The text is based on a talk given in Warsaw, Poland, on this topic, presented at a meeting of the European Materials Research Society in September 2010.

CARBON DIOXIDE IN THE GEOLOGICAL PAST

2023
AbstractWe trace CO2 concentrations through geological time. After the core and the crust were formed, 4.5 billion years ago (Gyr), Earth started to develop an atmosphere. An atmosphere that consisted of the exhaust gases from the interior: water vapour, nitrogen, and carbon dioxide.

Percolation behaviors of model carbon black pastes

Soft Matter, 2018
The percolation behaviors of a series of high-structured carbon black (CB) pastes (CB weight fractions 10–25 wt%, ethyl cellulose as the binder, α-terpineol as the solvent) were systematically investigated using analyses of rheology and impedance spectra together with characterization via ...

Chemically modified carbon paste and carbon composite electrodes

Electroanalysis, 1989
AbstractCarbon paste electrodes and composite carbon electrodes modified by 20% silica gel (30 μm) within the electrode material exhibit many properties typical of a strand of carbon fiber microelectrodes in voltammetric measurements. Charged and uncharged species were studied on these electrodes; phenol, ferricyanide, and potassium ethylxanthogenate ...

Electrochemical response of oligonucleotides on carbon paste electrode

Bioelectrochemistry, 2007
Electrochemical response of synthetic oligonucleotides with different DNA bases sequences was investigated to find relationships between a chain composition and a signal. All DNA mononucleotides present electroactivity at a carbon paste electrode yielding anodic peaks at potentials: 1.00 (GMP), 1.28 (AMP), 1.47 (TMP) and 1.53 V (CMP).
